POE::Loop::Tk implements the interface documented in the POE::Loop manpage.
Therefore it has no documentation of its own. Please see the POE::Loop
manpage for more details.
POE::Loop::Tk is one of two versions of the Tk event loop bridge. The
other, the POE::Loop::TkActiveState manpage accommodates behavior
differences in ActiveState's build of Tk. Both versions share common code
in the POE::Loop::TkCommon manpage. POE::Loop::Tk dynamically selects the
appropriate bridge code based on the runtime enviroment.
